How can you use estimation to check that you have placed the decimal point correctly in your product?
An estimate will give an indication of the order of magnitude of the answer. The decimal point determines the order of magnitude and so, if the two are in agreement, then the decimal point has been placed in the right place. However, if you did your arithmetic properly then there would be no need to do the extra calculations required for an estimate.
What else can I help you with?
How can you use estimation to place the decimal point in the quotient 42.56 divided by 22?

What can you find how finding a whole number estimate before your multiply the decimal can help you make sure your decimal placement is correct?
Not really.If you are competent in using the basic operations of arithmetic (+ - * /) and follow the riles as these apply to decimal numbers then the decimal point will be correctly placed and finding a whole number estimate will only mean additional calculations which serve no purpose. On the other hand, if you are not that competent then how can you be sure that the whole number estimate that you find is accurate?

How do you know when your decimal numbers are placed correctly?
You could try estimation to get an idea of the magnitude of the answer.
How can you use estimation to determine whether you have placed the decimal point correctly in the product?
A reasonable estimate will give an indication of the order of magnitude of the number. The order of magnitude is determined by the decimal point and so knowing the order can help in placing it.
How does estimating the answer help you to know that you placed the decimal point in the sum correctly?
It doesn't really. If you are a competent user of arithmetic operations on decimal numbers then this will only mean additional calculations simply to confirm something which you would have done correctly anyway. And if you are not competent, then who is to say that your estimation is more likely to be correct?
What are two methods for determining the placement of the decimal point in the product?
